Who would you dress up like at a convention?

I'm planning to go to the Atlanta Twilight convention in July. Unless this one is different, Creation Entertainment has been having a dress up like your favorite Twilight character event as part of the convention. I think I will dress up as Alice. Not only do I adore her character, but being 4'11" myself, I come the closest to pulling her off. I look nothing like Ashely Greene so I'll have to go for my idea of the "book" Alice. I do have the replica of the Cullen crest choker she wore in the movie. And I think I can dress similar to how she dressed in the movie.
